Question

!!!!!!!!!!!!!!!!HELP

Answer 1

You have to use this equation:
`a^(2) + b^(2) -c^(2)`

Explanation:

C is the hypotenuse but you need another one so you got to do

`x^(2) +8^(2) =17^(2)`

now you have to find
`x^(2)` which is

`x^(2) = 17^(2) - 8^(2)`

`x^(2) = 289 - 64`

`x^(2) = 225`

`x = √(255)`

`x = 15`
